Scott, of pobox.com, had the solution to the archive access issue.
In the Apache srm.conf file, I needed to have the following:
<Directory /home/mailman/archives/public>
Options FollowSymLinks
order allow,deny
allow from all
</Directory>
After adding that, and restarting httpd, it now works.
Now if only we could restrict access to private archives to members of the
list, using the email address as a login, and the list password as the
access password to see the archives...
Thanks for everybody's input.
